That is a spot on statement!
I've become pretty anal lately about diesel storage/treatment. Also, since I have a diesel fueled truck (with multi-injection type injection events), a TDI SUV (still under warranty with DPF & Cat), generators and tractor once I read
THIS ARTICLE I no longer purchase B20 diesel. I used to purchase it and yes it ran fine but that article made me rethink the long term effects on my small fleet of diesel engines (internals) in addition to
possible storage deterioration effects. Now, I've
standardized all my diesel fuel purchases and I only purchase B5 name brand diesel (Shell, Mobil, Chevron, etc.) even when B20 runs about 30 cents cheaper per gallon in my area.
I understand that all local diesel fuel comes down the line through the same distribution center with end use brand additives mixed at the racking terminal but to me its ALSO the handling/filtering/storage at the point of sale station that counts towards getting quality diesel fuel without any added contaminants (especially water). So with the least amount of BD as required by our state law (B5) and proper station handling/dispensing at high turnover stations I feel the diesel I purchase will store longer and in theory perform better.
However with that said, I wouldn't hesitate to run HHO in my gensets if it were available in bulk. Since I wouldn't be running it in "on-road vehicles" and because it would typically be shared for home heating purposes it wouldn't be sitting in long term static storage (routine turnover rate). Even if less routine turnover, that can be addressed with larger additive doses and good filtration.
I know the subject of BioDiesel is often heavily debated and older engines (without much in the way of pollution control or multi-injection events) seem to tolerate it better than later models (unless OEM B20 approved). My fuel choice is personal based on my existing fleet and my desire aimed towards
long term ownership, YMMV.
